This web site will allow you to download the boundaries and layers of
different countries, in Arc/INFO export format, from ESRI's Digital
Chart of the World data set. Our mapping function will give you a
preview of the data. The DCW was created in the 1990s. For a more current DCW project see VMap0 DCW

EPA Geospatial Data
Download files - To improve public health and the environment, the
EPA collects information about facilities or sites subject to
environmental regulation. The EPA Geospatial Data Access Project
provides a downloadable extensible markup language (XML) file, ArcGIS
Shapefile and Feature Class of these facilities or sites. Within the
file is key facility information, along with associated environmental
interests for use in mapping and reporting applications.
The EPA Geospatial Data Download files includes:

EPA Criteria Pollutant Shapefiles - Point data for each facility that releases the criteria pollutant to the environment. Data includes facility name, address, amount released, percent this facility's releases are of total national release and more. CO, NH3, NOX, PM10, PM2.5, SO2, VOC.

GDAL - Geospatial Data Abstraction
Library is a translator library for raster geospatial data formats
that is released under an X/MIT style Open Source license by the Open
Source Geospatial Foundation. As a library, it presents a single
abstract data model to the calling application for all supported
formats. It also comes with a variety of useful commandline utilities
for data translation and processing. The NEWS page describes the October
2008 GDAL/OGR 1.5.3 release.

GEO-DATA Explorer (GEODE) - Access,
view, and download information from geo-spatial databases containing a
broad spectrum of data produced by the USGS and other government
agencies.

GEOnet Names Server (GNS) provides access to the
National Geospatial-Intelligence Agency's (NGA) and the U.S. Board on
Geographic Names' (US BGN) database of foreign geographic feature names.
The database is the official repository of foreign place-name decisions
approved by the US BGN. Approximately 20,000 of the database's features
are updated monthly. Geographic Area of Coverage: Worldwide excluding
the United States and Antarctica.

Global Land
One-kilometer Base Elevation (GLOBE) Documentation. This is the
first version of documentation for the Global Land One-kilometer Base
Elevation (GLOBE) data set. GLOBE is an internationally designed,
developed, and independently peer-reviewed global digital elevation
model (DEM), at a latitude-longitude grid spacing of 30 arc-seconds
(30"). This report describes the history of the GLOBE project, the
candidate data sets, data compilation techniques, organization, and use
of the data base. The data are available on CD-ROM and the World Wide
Web.
